STOP-MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent No'. 770,467, dated September 20, 1904.

Application filed March 25, 1903.

To all whom it may concern:

Be it known that we, HENRY J. J ARRY, residing at Worcester, in the county of Worcester, and JOHN REGAN, residing at New Bedford, in the county of Bristol, State of Massa'chusetts, citizens of the United States, have jointly invented certain new and useful Improvements in Stop-Motions for Looms, of which the following is a specification.

Our invention relates to. warp stop mechanism for looms; and the object of our invention is to improve upon and simplify the construction of warp stop mechanisms ordinarily used in looms to stop the loom whenever the warp-thread breaks or becomes too slack, and particularly to improve upon the class of warp stop mechanisms shown and described in United States Letters Patent No. 665,713, of January 8, 1901.

In our improvements, as herein shown and described, a hunter carried on the lay is adapted to engage a movable dagger or arm on the breast-beam and through intermediate connections release the shipper-lever to stop the loom, when the detecting mechanism operates, on the falling of a drop device, to moveapivoted lever from under the projecting end of the dagger. The pivoted lever, which extends under and supports the dagger in its normal 3 position, has a pivotal motion in a direction transverse or at right angles to the longitudinal motion of the dagger, and usually before the dagger is engaged by the bunter said pivoted lever will be released and will move toward the dagger to assume its normal position under the same, but will strike against a shoulder or downward extension on the dagger and be held in that position until the dagger is moved endwise. When the dagger is moved endwise by engagement with the hunter and the extension on the under side of the dagger has passed beyond the engaging end of the pivoted lever, said lever will return to its normal position under the dagger, and on the forward movement of the dagger on the movement of the shipper-handle to its normal position the inclined surface or beveled end Serial No. 149,530. (No model.)

on the extension on the lower edge of the dagger will ride up on the projecting end of the pivoted lever and cause the dagger to automatically assume its normal position out of the path of the hunter on the lay; and, further, in our improvements we connect the filling-fork slide carrying the feelers of the filling-fork detector mechanism with the same lever with which the dagger above described is connected, which lever operates the shipperhandle, so that upon the breaking of a warpthread through the movement of the fillingfork slide the shipper-lever will be operated to stop the loom-that is, the lever intermediate the shipper-lever and the filling-fork slide-and the shipper-lever and the dagger of the warp stop mechanism is free to be moved either by the movement of the fillingfork slide or by the movement of the dagger of the warp stop mechanism independently of each other.

Our invention consists in certain novel features of construction of our improvements, as will be hereinafter fully described.

We have only shown in the drawings sufficient portions of a loom and portions of a warp stop mechanism of well known construction with our improvements applied thereto to enable those skilled in the art to which our invention belongs to make and use the same.

Referring to the drawings, Figure 1 is a right-hand end view or side elevation of a loom with sufficient parts thereon to illustrate the construction and operation of our improvements applied thereto. Fig. 2 is a detached detail of the bunter on the lay and the endwise-moving dagger and supporting pivoted lever. Broken lines show the lowered position of the dagger to be engaged by the hunter. Fig. 8 is a rear perspective View of the right-hand end, the breast-beam with our improvements applied thereto. Fig. 4: is a vertical cross-section on line 4 4, Fig. 3, looking in the direction of arrow a, same figure, and Fig. 5 is a longitudinal section through the plate and parts supported thereon, taken at apoint indicated by lines 5 5, Fig. 3, looking in the direction of arrow 6, same figure.

1n the accompanying drawings. 1 is the lay having in this instance bolted to its front edge on the right-hand end a hunter 2, the engaging end 2 of which in this instance extends above the lay and is in a position to engage the dagger of the warp stop mechanism on the forward movement of the lay in case the dagger is in its lowered position through the operation of the detector mechanism on the breaking of a warp-thread,

3 is the breast-beam on which is mounted the filling-fork slide 1, which carries the pivoted feelers or fingers 4 at its inner end to be engaged by the filling-thread on the bcating up of the lay to move said fingers and raise the hook connected therewith within the slide and prevent the engagement of the cam-lever 5, operated by the cam 6 on the bottom shaft 7, all in the usual way. In case there is no filling-thread to engage the feelers 4 and move the same, the filling-fork slide 1 is moved on the breast-beam by the cam-lever 5 in the ordinary way. The filling-fork slide 4 has a horizontal slot or opening 4: therethrough at its rear end, as shown in Fig. 4:, and into said opening to move freely therein extends the end of a centrally-pivoted lever 8. Said lever 8 is pivoted on the upper side of the breast-beam 3, in this instance on a stud 9,

and its oppositely-extending end 8 is in position to engage the shipper-lever 10 when it extends in the notch 10 leading out from the slot 10, in which the shipper-lever 10 moves in the usual way. It will thus be .seen that the backward movement of the fillingfork slide on the failure of a filling-thread to move the filling-feelers 4, the lever 8 by reason or its end extending into the opening 4 in the filling-fork slide 4: will be moved to cause the end 8 to engage the shipperlever 10 and move it out of the notch 10 and allow it to ship the belt and stop the loom. The end of the lever 8 also extends through an opening in the rear end of the endwisemoving knock-olf dagger 11 and is loosely attached to said dagger, in this instance by a wire loop 12, straddling the dagger and entering holes in the lever 8. The dagger 11 has an endwise motion on the plate 13, in this instance bolted to the top of the breast-beam 3 by bolts 14:, and the plate 13 has a side projection or flange 13, which extends between the filling-fork slide 4 and the endwise-moving dagger 11. Said flange is notched at 13, as shown in Fig. 4:, to receive the end of the lever 8. The dagger 11 extends at its front end through the vertical opening 15 in a guideplate 15, bolted to "the front of the breastbeam 3, as shown in Fig. 3. The dagger 11 is cut away on its lower front edge to form a shoulder or downward extension ll thereon to extend in the path of the lever which supports said dagger. The front edge of the extension 11 is inclined or beveled to cause it to ride up on the end of the dagger-supporting lever when said lever extends under said dagger 11 on the forward movement of the dagger.

Extending directly under the dagger 11 and pivoted on a stud 16 on the plate 15 is a supporting-lever 17, the hub 17 of which has an arm 17 extending out therefrom, which is connected by a link or wire 18 with the arm 19 on the hub 19 of the lever 19, pivotally mounted on a stud 20 on a stand 21, secured to the loom side. The lever 19 is connected by a connector or wire 22 to a lever 23, forming a part of the warp-stop detector mechanism.

The portion of the warp-stop detector mechanism shown at the right in Fig. 1 does not need to be described herein, as it is of the same construction and operation as the warpstop detector mechanism shown and described in Patent No. 665,713, above referred to.

From the above description in connection with the drawings the operation of our improvements will be readily understood by those skilled in the art. In case a warp-thread breaks on the operation of the warp-stop detector mechanism through connector 22 the lever 19 is moved in the direction of arrow 0, Fig. 3, causing the arm 19 to draw down, through link 18, the arm 17 of the lever 17 and cause the lever 17 to move out from under the dagger 11 and allow said dagger to drop, so that its front end will extend in the path of the hunter 2 on the lay, as shown by broken lines in Fig. 2. When the pivoted lever 17 is released, it will move back as the warp-actuated device is reset, so that its upper end will strike against the extension 11 on the lowered dagger 11; but it will be prevented from passing under said dagger. The engagement of the hunter 2 with the dagger 11 on the forward movement of the lay will move said dagger endwise or toward the front of the breast-beam, and through the engagement of the dagger with the lever 8, as above described, will move the lever 8 on its pivotal support and cause the end 8 thereof to engage the shipper-lever 10 and move it out of the notch 10 and allow it to operate to stop the loom. The return movement of the shipper-lever 10 preparatory to the starting of the loom moves the end 8 of the centrallypivoted lever 8 and causes said lever to move forward the dagger 11. The forward movement of the dagger 11 causes the inclined portion on the extension 11 to ride up on the le ver 17, extending under the dagger, and thus automatically put the dagger 11 in its normal position above the path of the hunter on the lay.

It will be understood that the details of construction of our improvements may be varied,

if desired, and that the same may be used in connection with any well-known style or construction of warp-stop detector mechanism.

We prefer to connect the filling-fork slide with the same lever with which the dagger of the warp stop mechanism is connected, as above described, so that either the fillingfork slide or the dagger will through one lever automatically operate the shipper-lever to stop the loom, and the operation of the shipper-lever by either the filling-fork slide or the dagger will be independently obtained.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a loom, the combination with the shipper-lever, the filling-fork slide, and the knockoff dagger of the warp stop mechanism, of a connection intermediate the shipper-lever and the filling-fork slide and intermediate the shipper-lever and the dagger, a guide-plate for the free end of the dagger, a movable suped to bear upon the side of the dagger, when the latter is in its lowered position, the-guideplate acting at such times to prevent sidewise or lateral deflection of the dagger, and a bunter for engaging the end of the dagger.

2. In a stopping mechanism for looms, the combination of a shipper-lever, a bunter car.- ried by the lay, the knock-off dagger of the warp stop-motion, a filling-fork slide having an elongated slot or opening therein, a pivoted lever on the breast-beam, said lever passing through and connected to the knock-0E dagger and entering the elongated slot of the filling-fork slide, a plate having a flange disposed between the knock-off dagger and weftfork slide, and means operative by the breaking of a warp-thread to permit the knock-01f lever to fall into the path of the bunter to thereby free the shipper-lever independent of movement by the weft-fork slide.
